8571836 ÷ 672 
We want to divide 8571836 by 672.

On to step 1:
672 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 672

On to step 2:
672 goes into 85 0 times with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Append the next digit (7) from the dividend to 85 and continue with: 857 / 672

Let's proceed to step 3:
The number 672 fits into 857 1 times, leaving a remainder of 185.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 672 from 857 and we're left with 185.
Include the next digit (1) from the dividend after 185, then repeat: 1851 / 672

Going ahead to step 4:
672 can be fit into 1851 2 times, resulting in a remainder of 507.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 1344 from 1851 and we're left with 507.
Grab the next digit (8) from the dividend, add it to 507, then carry on: 5078 / 672

Step 5:
The number 672 fits into 5078 7 times, leaving a remainder of 374.
The next digit of our result is 7. 
Result so far: 127.0
Subtract 4704 from 5078 to get 374.
Include the next digit (3) from the dividend after 374, then repeat: 3743 / 672

Moving on to step 6:
3743 divided by 672 is 5 with a remainder of 383.
Use 5 as the next digit of our solution. 
Result so far: 1275.0
Subtracting 3360 from 3743 leaves us with 383.
Take the next digit (6) from the dividend and append it to 383, then repeat: 3836 / 672

On to step 7:
3836 divided by 672 is 5 with a remainder of 476.
Put 5 as the next digit of the answer. 
Result so far: 12755.0
If we subtract 3360 from 3836, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Let's proceed to step 8:
If we divide 4760 by 672, we get 7 and a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 12755.7
If we subtract 4704 from 4760, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
If we divide 560 by 672, we get 0 and a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 12755.7
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 10:
When dividing 5600 by 672, we get 8 with a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 12755.708
Subtracting 5376 from 5600 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 11:
672 can be fit into 2240 3 times, resulting in a remainder of 224.
The number 3 becomes the next digit in our result. 
Result so far: 12755.7083
If we subtract 2016 from 2240, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 12:
The number 672 fits into 2240 3 times, leaving a remainder of 224.
Record the quotient 3 as the next digit in the result. 
Result so far: 12755.70833
Deduct 2016 from 2240 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final result is 12755.70833 with a remainder of 0.000224.
